I post my stories on several sites including Quotev (as SilverStrings), FFnet, Wattpad, and AO3. Probably most known for my interactive fan fiction. Personally, I think that's the best way to give a true reader insert experience. Stories I post on Wattpad are pretty much the OC versions of those. 

I don't have any currently ongoing works for Wattpad at the moment, but I hope you enjoy what I do have posted. I do have two interactive stories in the works that will eventually be converted to the OC format and published here.

I highly recommend checking out the guides written by @HatedLove6 -- especially her Mary Sue series. They're all incredibly well-researched and well-written.
